How can i make score keep updating after bool condition has been met on looping objects?

So my problem is i have a score that updates by 10points after the objects pass a specific coordinate. The thing is i have to objects to loop back to the starting poistion after they reach a certain coordinate so they can be run again. The thing is when they reach the score point nothing happens, an my guess is that it is becuase they pass the point once already, heres a script to help

 using UnityEngine;
 using System.Collections;
 
 public class scoredisplay : MonoBehaviour {
     public static int scoreValue;
     public GUIText guiScore;
     private Transform Obstacle;
     bool hasAwardedPoints = false;
 
 
 
 
 
 
     void Awake() {
         DontDestroyOnLoad (gameObject);
     }
 
 
 
 
 
     // Use this for initialization
     void Start () {
 
 
 
         Obstacle = transform;
         scoreValue = 0;
         guiScore.text = "Score: 0";
 
 
         }
         
 
 
 
 
 
     // Update is called once per frame
         void Update () {
         if (Obstacle.position.x < -12.5f && !hasAwardedPoints) {
                         scoreValue += 10;
                         guiScore.text = "Score: " + scoreValue;
                         hasAwardedPoints = true;
                 }
